The block to be erased is selected by using any valid address within that block. block memory maps The TMS28F400Axy is available with the block architecture mapped in either of two configurations: the boot block located at the top or at the bottom of the memory array, as required by different microprocessors. The TMS28F400AxB (bottom boot block) is mapped with the 16K-byte boot block located at the low-order address range (00000h to 01FFFh). The TMS28F400AxT (top boot block) is inverted with respect to the TMS28F400AxB with the boot block located at the high-order address range (3E000h to 3FFFFh). Both of these address ranges are for word-wide mode. Figure 1 and Figure 2 show the memory maps for these configurations. The TMS28F004Axy is mapped as the 8-bit configuration of the TMS28F400Axy, except that the least significant bit (LSB) is A0 instead of A−1. |
